Wesley hears Cordelia's warning at the last second and spins around to face his attacker. However, he doesn't need to defend himself because Angel already has his back.

He feels a surge of gratitude, smiles briefly and then scrambles over to where Cordelia is lying prone. He gathers her in his arms, trying to rouse her. She's covered in bruises and shallow cuts and lacerations. He prays that the damage isn't any more serious than that.

"Cordelia. It's alright, I've got you. Angel's here. We're going to get you out of here."
